I agree the control issue is definitely not perfectly solved - it's something they could reasonably improve in patches.
I almost wish they had stuck to the original aerial combat RTS that the early footage (and the Imperial Edition documentary) show. It would have maybe been a more natural fit to integrate with the "Dragon with jetpack" idea. Vincke posted a long blog about how it wouldn't mesh properly with the strategy level, so it's probably for the better overall, but the RTS element would have been stronger with that idea, I think.
